This invention appertains to new and useful improvements in means forflashing roofs and other structures requiring this protection.

The principal object of the present invention is to provide a means offlashing which will be simple and not susceptible to the development ofdefects very readily after installation.

Another important object of the invention is to provide a new form offlashing which can be installed by inexperienced help.

Other important objects and advantages of the invention will becomeapparent to the reader of the following specification.

als designate like parts, it can be seen that the brick is denoted bynumeral 5 which can be rectangular, square or of any other shape desiredand found necessary. The brick 5 will have at least one opening 6extending longitudinally therethrough adjacent one edge portion and thisedge portion is slotted longitudinally as at I with the slot extendinginto the said opening 6. It is preferable that the opening 6 be ofsquare or rectangular cross section so as to define the upper and lowershoulders 8--9.

Numeral l0 represents the flashing strip, one longitudinal edge portionof which is bent backwardly in a diverged direction as at l I so thatwhen the strip is inserted as shown in Figure 2 the bent back edgeportion will abut the shoulder B.

The strip It] may be lapped in this position and sealed as shown inFigure 3 by suitable sealing material I 2 or else the strip can bepulled outwardly and the inner edge portion will assume the deformationshown in Figure 3 and referred to by numeral l3, which of course willresult in a double assurance against displacement by reason of the factthat the inner edge portion is now engaging both of the shoulders 8-9.

Figure 1 discloses a conventional roof construction I4, the buildingwall structure I5 and a cornice Hi. This form of flashing may be used inconnection with the roof or with the cornice l6 or with both as shown inFigure 1.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeing to define a pair of opposed shoulders, a

flashing strip for disposition through the said slot and into theopening of the block, said strip being adapted to bear behind one of theshoulders, said strip being provided with a backwardly bent obliqueportion engaged against the inside of the opposed shoulder, said stripbeing adapted to bend adjacent the said backwardly bent portion so thatwhen a pull is exerted on the strip, the backwardly bent portion willmove to a position spanning the slot and engaging behind both of thesaid shoulders.
